The 131 number is the mass number: the sum of the number of protons and neutrons. Iodine has 53 protons and will have 53 electrons if its a neutral atom. To find the number of neutrons, just subtract the mass number with the number of protons 131 - 53 = 78 neutrons. See link below for periodic table.
With 131 particles in the nucleus, Iodine will have 78 neutrons. The atomic number of Iodine (53) never changes, and the atomic number of an element is the number of protons it has. Therefore, 131 particles (protons or neutrons) minus 53 protons = 78 neutrons.
Iodine has an atomic number of 53. The number of neutrons is always equal to the mass number minus the atomic number; in this instance 131 - 53 = 78 neutrons.
131. The number of nucleons (protons and neutrons) in the nucleus of any atom is the same as the mass number of the isotope that is suffixed to the element name.
Iodine-129 has 76 neutrons in the atomic nucleus.
78 - wikipedia is your friend ;)
there are 53 :)
the nucleons contain neutrons and protons in it
the number of nucleons ,,
In the nucleus of the atom. The protons and neutrons of an atom are together collectively known as nucleons.

The nucleus is the very dense region consisting of nucleons (protons and neutrons) at the center of an atom.
the nucleons contain neutrons and protons in it
They're called nucleons. The two types of nucleons are protons and neutrons. Protons are positively charged nucleons and determine, in an atom, what element that atom is. Neutrons have no charge and just supposedly add mass to an atom.

the number of nucleons ,,
Particles found in the nucleus of an atom are named as nucleons. There are mainly two type of nucleons. They are protons and neutrons. Protons are having positive charge but neutron is chargeless. To keep these nucleons together a particle known as pi mesons are exchanged between the nucleons.
Nucleons are particles are are included in the nucleus of an atom. These include neutrons and protons (and their anti-matter pairs).
In the nucleus of the atom. The protons and neutrons of an atom are together collectively known as nucleons.

An average phosphorus atom has 15 protons and 16 neutrons, and it has 31 nucleons.
The nucleus is the very dense region consisting of nucleons (protons and neutrons) at the center of an atom.
They are collectively known as nucleons, and together, all of them form the nucleus of an atom.
